title: Weakly stabilized primary borenium cations and their dicationic dimers.
abstract: Hydride abstraction from monocationic hydride bridged salts [H(H2B-L)2](+) [B(C6F5)4]¯ (L = Lewis base) generates an observable primary borenium cation for L = iPr2NEt, but with L = Me3N, Me2NPr, or several N-heterocyclic carbenes, highly reactive dicationic dimers are formed.
